DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0256 AM CST FRI JAN 26 2007
VALID 261200Z - 271200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
AN UPPER-LEVEL LOW OVER SRN QUEBEC WILL MOVE EAST...AS A SHORT WAVE
TROUGH AMPLIFIES S/SEWD FROM THE S-CNTRL CANADIAN PRAIRIES ACROSS
THE NRN GREAT LAKES/UPPER MIDWEST. THIS AMPLIFICATION WILL AID IN
THE EWD ACCELERATION OF A CLOSED LOW FROM FAR NRN MEXICO ONTO THE
SRN PLAINS. AT THE SURFACE...A MASSIVE AREA OF HIGH PRESSURE FROM
THE SRN PLAINS NEWD THROUGH THE OH VALLEY WILL WEAKEN AS IT BECOMES
CENTERED OVER THE SERN CONUS BY 12Z SAT.
...SRN AL/SRN GA/MUCH OF FL...
A DRY AIR MASS WAS IN PLACE ACROSS THE AREA THIS MORNING WITH DEW
POINTS IN THE 20S AND 30S UNDER MODEST NLY FLOW. WITH FULL
INSOLATION...TEMPERATURES WILL WARM FROM THE UPPER 50S N TO AROUND
70 S. THIS WILL PRODUCE CRITICALLY LOW RH VALUES FROM 20 TO 30
PERCENT...EXCEPT ALONG THE E COAST OF FL WHERE WINDS WILL BECOME
NELY AND ONSHORE FLOW DEVELOPS. THE LIMITING FACTOR TO A CRITICAL
AREA ISSUANCE WILL BE THE STRENGTH OF THE WINDS. WITH A LARGE AREA
OF HIGH PRESSURE APPROACHING...LOW-LEVEL WINDS WILL SUBSTANTIALLY
WEAKEN LATER THIS MORNING THROUGH THE AFTERNOON. SURFACE WIND SPEEDS
WILL BE AROUND 10 MPH OR LESS DURING THE PERIOD OF LOW RH.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0349 AM CST FRI JAN 26 2007
VALID 271200Z - 281200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
HIGHLY AMPLIFIED UPPER-LEVEL PATTERN WILL EXIST ACROSS THE CONUS
WITH A TROUGH OVER THE CNTRL/ERN CONUS AND A REX BLOCK CENTERED JUST
OFF THE W COAST. SURFACE LOW PRESSURE OVER THE CNTRL GREAT LAKES
WILL INITIALLY WEAKEN WHILE CYCLONE DEVELOPMENT OCCURS OFF THE LA
COAST. THESE LOWS WILL QUICKLY MOVE EWD REACHING THE ERN SEABOARD BY
12Z SUN.
...PIEDMONT AND COASTAL PLAINS OF THE CAROLINAS...
A MODERATE BELT OF 30 TO 40 MPH LOW-LEVEL W/SWLY FLOW SHOULD DEVELOP
EARLY SAT TO THE S OF THE CNTRL GREAT LAKES CYCLONE. ALTHOUGH THE
LOW IS EXPECTED TO WEAKEN THROUGH THE DAY WITH A COINCIDENT
WEAKENING OF THE SURFACE PRESSURE GRADIENT...DAYTIME HEATING WILL
ALLOW SOME MECHANICAL MIXING OF THE HIGHER MOMENTUM AIR ALOFT.
SUSTAINED SURFACE WINDS SHOULD REACH 15 TO 20 MPH. ALTHOUGH SOME
LOW-LEVEL MOISTENING WILL OCCUR WITH UPSTREAM DEW POINTS IN THE
20S...TEMPERATURES WILL ALSO WARM INTO THE UPPER 50S TO MIDDLE 60S.
THIS SHOULD LEAD TO MARGINALLY LOW RH VALUES AROUND 25 PERCENT.
